Editing Statistical Field Theory (section)

== <span style="color: #FFFFFF;">Remembering</span> ==
* '''Statistical Field Theory''' — The use of field theory techniques to study systems with a "Large number" of "Interacting particles" in the presence of "Randomness."
* '''Phase Transition''' — A "Sudden Change" in the state of matter (e.g., Ice melting, a Magnet losing its power).
* '''Ising Model''' — The "Atomic Model" of magnetism: a grid of "Arrows" (Spins) that can point "Up" or "Down" and want to be like their "Neighbors."
* '''Critical Point''' — The "Edge of Chaos" where a system is "Between" two states (e.g., Water is "Both" liquid and gas).
* '''Entropy (S)''' — The measure of "Disorder" or "Randomness" in a system.
* '''Free Energy (F)''' — The "Battle" between "Energy" (which wants things to be Orderly) and "Entropy" (which wants things to be Messy): $F = E - TS$.
* '''Correlation Length''' — How far a "Wiggle" in one part of the system "Affects" the rest of the system.
* '''Universality''' — The "Magic" of physics: the discovery that "Boiling Water" and "Magnets" follow the **Exact same math** near their critical points.
* '''Partition Function (Z)''' — The "Master List" of all "Possible States" of a system; the most important number in statistical physics.
* '''Renormalization Group (RG)''' — A "Zoom-In" technique used to see how the "Big behaviors" are built from "Small behaviors."
